DETAILED DESCRIPTION

[0029] Referring to FIG. 1, there is shown flow-through device 10, which includes cylindrical tube 12, porous plates 14, 16 (made of inert plastic porous frits or glass or Teflon), and porous solid media 18 (only partially shown in the figures) between porous plates 14, 16. Tube 12 can be made from glass, polyethylene, polypropylene, Teflon and other plastics. Media 18 can take various forms depending on the application. Media 18 can be silica, other conventional chromatography media, or solid media that has attached active components such as scavengers, coupling agents, catalysts, or catalyst removers.

[0030] Referring to FIG. 2, flow-through device 10, containing a sample to be processed therein, is shown being subjected to microwave energy in microwave chamber 20. In some applications, the processing involves removal of a dissolution solvent in which a sample compound of interest is dissolved. In other applications, the media plays an active role in chemical reactions taking place in the flow-through device. In some applications a conventional microwave oven can be used as the microwave chamber. In some other applications, it is better to use a microwave chamber with more precise controls, e.g., units available from Personal Chemistry, CEM or Milestone, Inc. (Monroe, Conn.).

[0031] Use of Flow-Through Device 10 for Removal of Dissolution Solvent

[0032] As is described in the above-referenced patent, when chemists optimize liquid chromatographic separations conditions, they may need to dissolve the sample mixture in a dissolution solvent which may be nonideal for elution. This can result in poor separation and poor recovery of desired components in a chromatography column. For example, polar solvents such as methanol, isopropanol (IPA), acetone, and ethylacetate (EtOAc) can interfere with chromatographic purification. The above-referenced patent describes adding a sample dissolved in a dissolution solvent to the top of the flow-through device (referred to as a sample module in the patent), where it is drawn into the media by capillary action. The sample absorbs onto the media, and the dissolution solvent is then removed by placing the flow-through device in a vacuum chamber and/or applying heat prior to placing the device in, or otherwise connecting it to, a chromatography column.

[0033] In order to avoid the use of a vacuum chamber or heat and to accelerate the drying of the solvent, one can instead subject the sample to microwave energy in microwave chamber 20. For example, subjecting flow through devices available from Biotage under the Flash 12 trade designation and containing one ml of the solvents IPA, EtOAc, acetone, methanol, and dichloromethane (DCM) in a conventional microwave oven (power set at 30) for 60 seconds resulted in the following percentage evaporations respectively, 82%, 72%, 96%, 88% and 92%. In general, removal of 80% of the polar solvent eliminates the interference of the chromatographic separation. When one is using the microwave chamber and sample module solely for the purpose of removing a dissolution solvent prior to chromatography, one may wish to use an inert media (e.g., sea sand or diatomaceous earth) instead of silica, in order to minimize the possibility of hydrolyzing acid sensitive groups. When polar solvent is removed, sample retention is enhanced, compound resolution is improved and tighter elution bands result. There also are increased separation efficiencies, lower volume fractions and increased loading capacities.

[0034] Referring to FIG. 3, flow-through device 10 (with a preabsorbed sample therein) is used in chromatography system 30, which also includes a source of solvent 32 (different than the polar dissolution solvent), pump 34, liquid chromatography column 38, and sample fraction collection system 40. In this system, solvent from source 32 is pumped by pump 34 through flow-through device 10 and chromatography column 38, carrying sample from device 10 thereto, to perform the chromatographic separation of the sample. FIG. 4 shows how flow-through device 10 is sized to fit entirely within the end 42 of chromatography column 38 containing a separation media 44. In device 10, the upper plate 14 is spaced from the upper end so that tubular member 12 defines a receiving region adapted to receive the lower end 45 and the lower compressible sealing ring 46 of sealing head piece 48, which also has an upper compressible sealing ring 50 for providing a seal to the chromatography column 38.

[0035] Alternatively, instead of inserting the device 10 into chromatography column 38, device can be placed in a remote holder 70 and connected to the chromatography column by a solvent tube 72, as shown in FIG. 6. Solvent could also be added to device 10, which is then placed directly into column 38, or remote holder 70 connected to chromatography column 38 by tube 72.

[0036] Device 10 can also be implemented in different forms, as shown in FIGS. 7-9.

[0037] Referring to FIG. 7, flow-through device 80 includes short plastic tube 82, which has a lower inert plastic porous frit 84 inserted so as to be flush with the bottom of tube 82. Tube 82 is then filled with a solid support 86 (e.g., porous media) to a pre-determined fill level, and a second inert plastic porous frit 88 is inserted. In this embodiment this top frit 88 is not flush with the top of the tube 82 and holds the solid support 86 in a stable form during shipping and ensures “plug flow” during use. In this embodiment the tube has a chamfer 90 on the top edge which eases insertion of both lower and upper frits 84, 88. In this case where the upper porous frit 88 is below the top of the tube 82, frit 88 may or may not form a sealing region 92 to allow a sealing head to be inserted which may or may-not be in contact with the top frit.

[0038] Referring to FIG. 8, flow-through device 100 includes short plastic tube 102, which has a lower inert plastic porous frit 104 inserted so as to be flush with the bottom of the tube 102. Tube 102 is then filled with a solid support 106 (e.g., porous media) to a pre-determined fill level, and a second inert plastic porous frit 108 is inserted. In this embodiment this top frit 108 is flush with the top of the tube 102 and holds the solid support 106 in a stable form during shipping and ensures “plug flow” during use.

[0039] Referring to FIG. 9, flow-through device 110 includes a longer plastic tube 112, which has a lower inert porous frit 114 inserted so as to be flush with the bottom of the tube 112. The tube is then filled with a solid support 116 (e.g., porous media) to as pre-determined fill level, and a second inert plastic porous frit 118 is inserted. In this embodiment this top frit 118 is not flush with the top of the tube 112 and holds the solid support 116 in a stable form during shipping and ensures “plug flow” during use. In this embodiment the tube 112 has a liquid receiving region 120 to enable wash solvent to be added after the liquid reaction has been absorbed.

[0040] Use of Flow-Through Device 10 as a Reaction Chamber

[0041] Flow-through device 10 can also be used as a reaction chamber in which the solid media includes attached active components such as scavengers, coupling agents, catalysts, or catalyst removers that assist in a chemical reaction therein. In this application, device 10 serves as a reaction chamber for solid phase organic synthesis (SPOS) or solid-assisted synthesis (SAS). In typical SPOS, a desired product (e.g., a small organic molecule being created as part of a combinatorial library) is synthesized on a bed; reactants and excess reagent stay in solution, and, at the end of the synthesis process, the excess reagents are washed out. In typical SAS, solid supports are used to hold reagents, catalysts for synthesis or chemoselective scavengers used to remove excess reactants during purification; this approach when applied to solution phase typically requires a long time for completion and involves many manual steps including washing and extractions.

[0042] An example in which device 10 is used to facilitate scavenging of excess reagents is shown in FIG. 5. In this example, reagent A and reagent B are introduced into a flow-through device 10 that includes solid media 18 with attached nucleophile scavengers N and attached electrophile scavengers E. Reagents A and B combine to form the Product, and excess reagent A and excess reagent B are removed by the scavengers, resulting in a Purified Product, which is removed from device 10 in liquid form. The reaction can take place at room temperature or be aided by application of microwave energy (in microwave chamber 20 in FIG. 2) or conventional heat (e.g., from a hot plate) or a UV lamp. The use of microwave energy is superior because it results in an extremely short reaction time. In a reaction arrangement where, following synthesis, the desired product is purified in a chromatography column, flow-through device 10 provides for ease of introduction of the sample into the chromatography column as described in the above-referenced patent. Where it is desired to remove solvent prior to purification in the chromatography column, microwave energy can also be used to provide fast solvent evaporation. By using microwave synthesis on chemical samples and/or reagents in flow-through device 10 (with or without microwave drying) and then directly connecting device 10 to chromatography column 38 for separation and purification, one can potentially synthesize and purify new compounds in less than one hour.

[0043] Examples of nucleophile scavengers N are TsCl scavengers and NCO scavengers. These scavengers can be used to remove excess nucleophiles including amine, hydrazine, alcohols and organometallics.

[0044] Examples of electrophile scavengers are amino scavengers, TsNHNH₂ scavengers, and SH scavengers. The amino scavengers can scavenge acid chloride, sulfonylchloride and isocyanates. The TsNHNH₂ scavengers can scavenge aldehydes and ketones. The SH scavengers can scavenge alkylating agents, ranging from octyl bromide to benzyl bromide. Other electrophile and nucleophile scavengers can be used.

[0045] In addition, base scavengers, e.g., quaternary amine, can be used as a general base to quench reactions, neutralize amine hydrochlorides or to scavenge a variety of acidic molecules like carboxylic acids or acidic phenols.

[0046] Also, acid scavengers, e.g., TsOH and COOH, can be used. E.g., solid media with attached TsOH can be used as an equivalent to the strong cation-exchange resin, Amberlyst A-15 (Rohm & Hass). The device 10 with TsOH attached to the solid media can be used for removal of basic compounds, e.g., primary, secondary and tertiary amine, by quaternary salt formation. Also it can be used for quenching reactions with aqueous or soluble organic acids and for Boc-deblocking by catch and release of amine derivatives.

[0047] Coupling agents, such as DCC, HOBt and NHS, can also be attached to solid media and used for the synthesis of amides and esters. A catalyst, e.g., TsOH can also be attached to a solid media and used as a catalyst for esterification.

[0048] A catalyst remover can also be attached. E.g., DEAM attached to a solid media is highly efficient in scavenging oxopilic inorganic and organometallic complexes, including those of boron, titanium and tin. This resin can be used to quench reactions and remove metallic reagents, catalysts or byproducts.

[0049] In addition to synthesis reactions, sample module 10 can be used to carry out other reactions, e.g., one or more of the following reactions:

[0050] i. Organometallic nucleophilic additions (e.g. Grignards, organocuprates, lithiates, etc.)

[0051] ii. Electrophilic additions to carbon-carbon multiple bonds.

[0052] iii. Sigmatropic rearrangements.

[0053] iv. Cycloadditions.

[0054] v. Thermal eliminations.

[0055] vi. Reductions (including hydrogenations).

[0056] vii. Oxidations.

[0057] viii. Multi-component condensations.

[0058] ix. Functional group interconversions.

[0059] x. Unimolecular rearrangements.

[0060] xi. Reactions involving transition metals.

[0061] xii. Aromatic substitutions.

[0062] xiii. Free-radical reactions.

[0063] xiv. Reactions of carbonyl compounds.

[0064] xv. Nucleophilic substitution reactions.

[0065] The reactions already described, including those involving the various scavengers, coupling agents, catalysts and catalyst removers, can be promoted and accelerated by placing the device 10 with the indicated solid media and reagents in microwave chamber 20 and applying microwave energy. In addition, the efficiencies of the reactions are improved such that the amount of excess reagents needed can be reduced. Alternatively, the device can be subjected to other forms of energy, including other forms of radiated energy, to promote and accelerate the reactions.

[0066] Use of flow-through device 10 as described can eliminate the manual manipulation involved in cleaning up a sample through extractions and washing and also provides a convenient reaction vessel.

[0067]FIGS. 10 and 11 show further alternative flow-through devices 200, 202.

[0068] Referring to FIG. 10, flow-through device 200 includes a vessel 204 made of microwave transparent material (glass or plastic), a porous frit or screen 206 across vessel 204 at the top of the vessel, and inflow line 208, which extends to the bottom of vessel 204, and outflow line 210, which begins above porous frit or screen 206. The interior region 212 of vessel 204 may or may not include reactive media, which could be porous or solid. Inflow line 208 and outflow line 210 may or may not be made of microwave transparent material. In use, reagents are placed in device 200, which is then placed in a microwave oven (e.g., microwave chamber 20 in FIG. 2) and used as a reaction vessel during application of microwave energy. After reacting the reagents, an assembly including inflow line 208 and outflow line 210 is inserted into the top of vessel 204, with inflow line 208 passing through porous frit or screen 206. Inflow line 208 is connected to a source of solvent (e.g., source 32 in FIG. 3) and outflow line 210 is connected to a chromatography cartridge (e.g., column 38 in FIG. 3) and liquid is passed through inflow line 208, upward through region 212 and porous frit or screen 206 and out through outflow line 210 to the chromatography cartridge.

[0069] Referring to FIG. 11, flow-through device 202 includes a vessel 214 made of microwave transparent material (glass or plastic), a porous frit or screen 216 across vessel 214 at the bottom of the vessel, inflow line 218, which ends at the top of the vessel 214, and outflow line 220, which begins at the bottom of vessel 214 and passes out of the bottom of vessel 214. The interior region 222 of vessel 214 may or may not include reactive media, which could be porous or solid. In use, reagents are placed in device 202, which is then placed in a microwave oven and used as a reaction vessel during application of microwave energy. After reacting the reagents, inflow line 218 is inserted into the top of vessel 214, and outflow line 220 is connected to a chromatography cartridge, and liquid is passed through inflow line 218, downward through region 222 and porous frit or screen 216 and out through outflow line 220 to the chromatography cartridge.

[0070] Nonporous or porous media (e.g., solid beads coated with a reactive media) can be used in the embodiments of FIGS. 1-4 and 6-11. The vessels of all embodiments of FIGS. 1-4 and 6-11 (including tubular member 12) can be made of glass or other microwave transparent materials.

[0071] The device of FIG. 10 or 11 can also be utilized to react the samples in an appropriate solvent and then drive off the solvent using microwave or other energy prior to introducing a chromatographically suitable solvents. A polar solvent can be driven off using heat, and this can also be accomplished using the microwave as the source of energy that heats up the solvent.
